Net-Zero Energy Home in Cupertino

Earth Bound Homes is involved with several ultra-green homes and this one in California deserves a mention. It was designed by Bill Leddy, LMS Architects, and built by Earth Bound Homes for David and Stephania Kaneda, receiving a Green Point Rated score of 268 and LEED Platinum certification.

Behind the paper, you’ll find a 2,400 square-foot home that’s net-zero energy — it uses as much energy as it produces on an annual basis — and zero carbon — it uses only electricity and solar hot water with no carbon-based fuels.

The master bedroom and primary living spaces have a southern orientation and insulated concrete floors that absorb warmth in the winter. In the summer, the owners use external shades to control solar heat gain.

For water savings and conservation, Kaneda Residence has low-flow plumbing fixtures, native landscaping, permeable pavers, and a gray water system that harvests bathroom water for irrigation.
